In this post, we will learn how to find the Convex Hull of a shape (a group of points). We will briefly explain the algorithm and then follow up with C++ and Python code implementation using OpenCV. What is a Convex Hull? Let us break the term down into its two parts — Convex ...
1. 单目视觉三维重建问题 在前面的文章中,笔者用SIFT提取特征后用radio测试剔除了匹配中异常的特征点,然后根据匹配合格的特征点计算基础矩阵和本征矩阵,对本征矩阵SVD分解来估计和构造透视矩阵,根据透视矩阵和齐次坐标变换后的特征点三角化获得特征点在三维空间中的坐标。 (1)找不到外极线 对于运动范围过大的两幅图...
